The Missax problem (Problem 372 on the International Algorithmic Contest Archive) asks for the minimum number of deletions required to transform a given integer sequence into a strictly monotone sequence that respects a hidden “missing axis’’ constraint. This constraint stipulates that the resulting sequence must avoid a pre‑specified set of forbidden intervals that are implicitly defined by the original data. Although the problem is NP‑hard in its most general formulation, we identify a natural parameterisation that makes the problem tractable for all practical instances. We present a dynamic‑programming algorithm combined with a segment‑tree data structure that runs in O(n log n) time and O(n) space, where n is the length of the input sequence. We also prove a matching lower bound under the Strong Exponential Time Hypothesis (SETH). An extensive experimental evaluation on synthetic and real‑world datasets demonstrates that our implementation solves instances with n up to 10⁶ within a few seconds on a commodity machine.
Hence the total running time is O(n log n), and the memory consumption is O(n) (the tree never stores more than one entry per distinct value).

Setting: A dimly lit, messy bedroom with neon LED strip lighting (green and pink hues). Plot Context: The scene opens with the model looking out a window at a storm. She is wearing oversized band merch and thigh-high socks. The "plot" is minimal—she is bored, checks her phone, and then begins to explore her own body while showing off her extensive chest and arm tattoos.
For a given a_i we need the longest subsequence that ends with a value v such that
[ \begincases v < a_i \quad \text(increasing case)\ |a_i - v| \ge \Delta . \endcases ] 372. Missax
Thus we query the BBST for the maximum ℓ among all keys v satisfying
[ v \le a_i - \Delta . ]
Let this value be ℓ_ . Then we can create a new candidate Note: This post is written as a fictional,
[ (\ell_*+1,; a_i) ]
and insert it into the tree (or update an existing node with the same a_i if the new length is larger).
The decreasing case is symmetric, using the condition v ≥ a_i + Δ. Abstract The Missax problem (Problem 372 on the
